Ghost. Lu. Patina. Sunny. Four kids from wildly different backgrounds with personalities that are explosive when they clash. But they are also four kids chosen for an elite middle school track team -- a team that could qualify them for the Junior Olympics if they can get their acts together. They all have a lot to lose, but they also have a lot to prove, not only to each other, but to themselves. Ghost has a crazy natural talent, but no formal training....

Sunny, the Defenders' best runner, only runs for his father, who blames Sunny for his mother's death, but with his coach's help Sunny finds a way to combine track and field with his true passion, dancing.
